NPDES EXAM QUESTIONS AND
ANSWERS 100% ACCURATE
MS4s - ANSWER-Municipal separate stormwater systems
What are the objectives of the storm water regulations for small MS4s? - ANSWER-
purpose of this portion of the storm water program is to designate additional sources
that need to be regulated to protect water quality and to establish a comprehensive
storm water program to regulate these sources. (Because the storm water program is
part of the National Pollutant Discharge Elimination System (NPDES) Program, you
should also refer to section 122.1 which addresses the broader purpose of the NPDES
program.)
(c) Storm water runoff continues to harm the nation's waters. Runoff from lands modified
by human activities can harm surface water resources in several ways including
changing natural hydrologic patterns and elevating pollutant concentrations and
loadings. Storm water runoff may contain or mobilize high levels of contaminants, such
as sediment, suspended solids, nutrients, heavy metals, pathogens, toxins, oxygen-
demanding substances, and floatables.
(d) EPA and the Department strongly encourage partnerships and the watershed
approach as the management framework for efficiently, effectively, and consistently
protecting and restoring aquatic ecosystems and the public health
NPDES general permit - ANSWER-Area or activity umbrella permit
Effluent - ANSWER-means the discharge from a waste disposal system;
(22) "Effluent limitations" means restrictions or prohibitions of chemical, physical,
biological, and other constituents which are discharged from point sources into State
waters, including schedules of compliance;
POTW - ANSWER-Publicly Owned Treatment Works
Waters of the State - ANSWER-lakes, bays, sounds, ponds, impounding reservoirs,
springs, wells, rivers, streams, creeks, estuaries, marshes, inlets, canals, the Atlantic
Ocean within the territorial limits of the State, and all other bodies of surface or
underground water, natural or artificial, public or private, inland or coastal, fresh or salt,
which are wholly or partially within or bordering the State or within its jurisdiction
Conditions applicable to all permits - ANSWER-Duty to comply
Duty to reapply
Need to reduce or halt activity not a defense
Duty to mitigate
Proper operation and maintenance
